      <p>
            The <a href="../api_reference/C/envfailchk.html" class="olink">DB_ENV-&gt;failchk()</a> method now has a new option to notify 
            environment processes of an application failure as soon
            as possible. This option causes any thread waiting on a
            mutex owned by a crashed process to return <a href="../programmer_reference/program_errorret.html#program_errorret.DB_RUNRECOVERY" class="olink">
            DB_RUNRECOVERY</a> instead of hanging.
        </p>
      <p>
            This option is enabled at compile time with the new
            configure option 
            <a class="link" href="build_unix_conf.html#build_unix_conf.--enable-failchk_broadcast">
                --enable-failchk_broadcast</a>.
            When enabled, this option provides a new timeout. It also 
            provides new events that notify the application when a
            thread is about to return <a href="../programmer_reference/program_errorret.html#program_errorret.DB_RUNRECOVERY" class="olink">
            DB_RUNRECOVERY</a>.
